High Noon hard seltzers are generally keto friendly. A standard 12-oz can contains around 4 to 5 grams of carbohydrates and roughly 2.6 grams of sugar, which fits comfortably within the 20 to 50 grams of daily carbs most keto dieters aim for. That said, the carb count varies slightly by flavor, and alcohol itself has effects on ketosis worth understanding before you crack one open.
Carbs by Flavor and Line
High Noon’s vodka-based seltzers are made with real fruit juice, sparkling water, vodka, and natural flavors. The use of actual juice rather than artificial sweeteners is part of the brand’s appeal, but it also means each flavor carries a small amount of natural sugar. Across the vodka line, you’re looking at about 2.6 grams of sugar and 4 grams of total carbs per 12-oz can, with 100 calories.
The tequila-based Fiesta line runs slightly higher. Grapefruit comes in at 4.3 grams of carbs, while lime is the highest at 5.0 grams. Blood orange and prickly pear land around 4.9 grams each. These are still low numbers in keto terms, but if you’re tracking closely, the tequila flavors will cost you about one extra gram of carbs compared to the vodka options.
High Noon also sells larger 700ml cans (about 24 oz). The brand markets these as 100 calories with no added sugar, but keep in mind you’re drinking roughly double the volume of a standard can. That means the carb load roughly doubles too, putting you closer to 8 to 10 grams per container.
How High Noon Fits a Daily Carb Budget
A standard keto diet caps daily carbohydrate intake at under 50 grams, with stricter approaches targeting 20 grams. One can of High Noon uses up about 4 to 5 grams of that budget. If you’re on the more generous 50-gram limit, a single can represents less than 10% of your daily allowance. Even two cans would leave plenty of room for food throughout the day.
On a strict 20-gram plan, the math gets tighter. Two cans could eat up nearly half your carb budget before you’ve had a meal. If you’re keeping carbs that low, sticking to one can and planning the rest of your meals around it is the safer approach.
Why Alcohol Slows Fat Burning
The carb count is only half the story. Alcohol has a separate, direct effect on the fat-burning process that powers ketosis. Your liver breaks down both alcohol and fat using the same chemical helper (a molecule called NAD+). When alcohol is present, your liver prioritizes processing the alcohol first. This effectively puts fat burning on pause until the alcohol is fully metabolized.
This doesn’t necessarily kick you out of ketosis, but it slows it down. Your body won’t be producing ketones at the same rate while it clears the alcohol from your system. For one or two drinks on an occasional evening, this is a temporary stall. For frequent or heavier drinking, the repeated interruption can meaningfully slow progress. The effect has nothing to do with carbs. It happens with any alcoholic drink, even zero-carb spirits.
How High Noon Compares to Other Options
- Plain spirits (vodka, tequila, whiskey): Zero carbs on their own, but mixers add up fast. A vodka soda with a lime wedge is the lowest-carb option available. High Noon’s 4 to 5 grams of carbs is the trade-off for convenience and flavor.
- Beer: Most regular beers contain 10 to 15 grams of carbs per serving. Even light beers typically run 3 to 6 grams, putting them in roughly the same range as High Noon but with less flavor variety.
- Wine: A 5-oz glass of dry wine has about 3 to 4 grams of carbs. Comparable to High Noon, though sweeter wines climb much higher.
- Other hard seltzers: Most competing brands (White Claw, Truly) land at 1 to 2 grams of carbs per can because they use artificial sweeteners instead of real juice. If minimizing every gram matters to you, those are technically lower. High Noon’s slightly higher count comes from using actual fruit juice.
Tips for Drinking High Noon on Keto
Choose vodka-based flavors over the tequila Fiesta line if you want to shave off a gram or two of carbs. Stick to the standard 12-oz cans rather than the 700ml format so you can track intake more precisely. Eat a meal with protein and fat before drinking, since alcohol on an empty stomach is absorbed faster and can amplify its effects on blood sugar and appetite.
Count each can as roughly 5 grams of carbs in your tracker to give yourself a small buffer, since nutrition labels on alcoholic beverages aren’t regulated as tightly as food labels. And if you notice your weight loss stalling despite staying under your carb limit, the alcohol’s temporary brake on fat oxidation is the most likely culprit, not the carbs in the drink itself.
